摘要： Methods and devices are provided to assist in providing multiple devices access to a surgical site through a single port. In one exemplary embodiment an access device includes a body having a plurality of ports. The ports can include at least one primary instrument port and at least one secondary instrument port. A self-sealing passageway can be disposed between the primary and secondary instrument ports to allow communication between the two ports. As a result, a surgical instrument can be repositioned from one port to another without removing the instrument from the access device. In one embodiment a combined end effector nominal width of surgical instruments disposed in the ports can be greater than a diameter of the primary instrument port and/or a diameter of the body of the access device. Exemplary systems and methods for performing procedures using multiple devices in a single surgical opening are also provided.

摘要： A medical apparatus and method useful for positioning a device, such as an endcap, on an end of an endoscope, is disclosed. The apparatus can exert a pulling force on the endoscope through the endcap while a pushing force is applied to the endcap. The apparatus can be used to press an endcap onto the distal end of an endoscope without grasping by hand a sheath in those applications where the endoscope is disposed in a sheath.

摘要： Devices and methods are provided for penetrating tissue and/or effecting movement of devices relative to tissue. In general, a surgical instrument is provided having an at least partially fabric-covered distal tip that be used to at least partially penetrate tissue by contacting the tissue with the fabric and rotating the fabric to “drill” into the tissue. The surgical instrument can be configured for delivery proximate to tissue through a working channel of a delivery device and can include an elongate shaft having in its distal portion an end effector at least partially covered in fabric. The fabric, the end effector, and/or the shaft can rotate, thereby allowing at least the fabric to penetrate the tissue and, if sufficiently rotated, causing an opening to form in the tissue. The surgical instrument and/or the delivery device can be advanced through the opening.

摘要： In accordance with the present invention there is provided a method for suturing tissue using a needle holder device, The device includes a handle for holding it, the handle has distal and proximal ends. The device also has right and left arms extending distally from the handle. The arms of the device have proximal ends attached to the handle and distal ends having grippers attached thereto for gripping and releasing a needle. The device includes at least one mechanism for moving the distal ends of the arms closely adjacent to one another and for passing the needle from one gripper to the other and thereafter for moving the distal ends of the arms further apart from one another. The right gripper is holding a needle having a suture attached thereto. The method first involves moving the distal ends of the arms apart from one another and manually inserting the needle into the tissue and back out again. Thereafter, the method involves actuating the mechanism so as to move the arms closely adjacent one another so that the left gripper holds the needle, the right gripper releases the needle. Then the method involves moving the distal ends of the arms further apart from one another. Lastly, the method involves removing the needle from the tissue.

摘要： A clip, clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.

摘要： Surgical devices are disclosed herein that generally include an intracorporeal elbow joint to facilitate translational movement of an end effector while allowing a body portion of the surgical device and a trocar or working channel through which the device is inserted to be maintained in a fixed angular orientation relative to the patient. This allows a plurality of such devices to be used effectively with a single incision or access device. Such devices also generally provide end effector movement with six degrees of freedom, while maintaining a mechanical linkage between the user and the end effector and while mimicking and/or mirroring natural user movement. Various methods related to such devices are also disclosed.
